Sprint has been mum about its 2011 lineup throughout this whole year until yesterday, when we finally got a break and caught wind of not 1 but 3 upcoming Sprint Android devices - the Nexus S 4G, the EVO 3D, and the EVO View tablet. The rumors were dropped to both Engadget and AndroidAndMe by an anonymous tipster, but both sites seemed confident in their sources, meaning it wasn't the first time the same credible tipster provided reliable information.
